Chefs with Daily Specials

I was wondering if any of you frequently update specials/menus on facebook and your website? What is your process for doing it. Do you use menuplatform.com? I would really appreciate your input/feedback on the easiest way to update menus online

I use a tumblr site designated just for specials and the process put into creating them, pics/recipes/etc... people follow it and can get updates once I post them and they can share them, it allows you to add and edit quickly on the fly without needing to know much about web design at all, the templates they provide for free are quite nice. It also gives kind of a modern/edgy vibe
